R&D Battery Cathode Current Collector

1.Production introduce

Carbon-coated aluminum foil is a new type of battery cathode substrate. Compared with traditional aluminum foill carbon-coated aluminum foil has the advantages of good electrical conductivity, low intemal resistance, strong mechanical properties and good toughness. It can avoid short circuits caused by burrs and improye the adhesion of electrode materials. It increase the discharge capacity of the battery and extend the service life of the lithium-ion battery.。

Application:

Cathode of lithium ion battery, super capacitor
